Hi

How can i do material evaluation/Validation in hyper elastic material model.
How can i choose the right material model(Ex-moone-revlin, marlow etc.)

Regards,
Shantanu

RE: Material Evaluate of Hyper elastic.

Have you read up on existing work on the same? The material model you choose depends on what you want to model- for example, you get Mooney-Rivlin with certain assumptions/simplifications applied on the Ogden model, and you get the Neo-Hookean on further simplifying the Mooney-Rivlin model. They are all characterized by their strain energy definitions, and you pick what suits you best.
Abaqus also has an option of entering experimental data. If you have data for the model you are considering, you could enter that, see what kind of SEF Abaqus picks, and go from there. I haven't ever used this option though, and am not a 100% sure that it will work. Out of curiosity, what are you trying to model?
